To all whom it may concern:

Be it known that I, Errors A. SPAGNOLO, a; subject of the King of Italy, residing at VVoonsocket, in the countyof Providence and State of Rhode Island, have invented new and useful Improvements in Shock- Absorbers, of which the following is a specification.

My invention pertains to shook absorbers ifor use on automobiles and other vehicles having spring-supported bodies, and it contemplates the provision of a simple, compact and durableshock absorber, calculated to efiiciently counteract the movements of the body of a vehicle relative to the axles thereof, and vice versa, as when the vehicle is passing over a rough road, andin that .way' 'prevent the transmission oi shock and jar to the passengers in the body.

With the foregoing in mind the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which: Y

Figure l is a side elevation of the shock absorber constituting the preferred embodiment of my invention. Figs. 2 to 6 are perspectives of appurtenances usedin the em bodiment shown in Fig. 1. 3 Fig. l isa view illustrating a modified shock absorber in side elevation as properly applied to a vehicle. Fig. 2 is an enlarged view, partly in side elevation and partly vertical section, of the modified shock absorber er se. .Fi 3 is a view of the absorber, ta en at rig t angles to Fig. 2. Fig. 4 is adetail horizontal section, taken in the plane indicated by the line H of Fig. 2, and showing the means for increasing the frictional contact between. the resilient U-shaped members of the device.

Referring by numerals to. the drawings, and more particularly to Figs. 1 to 6 thereof-: 4 is the lower U-shaped member of my novel shock absorber. The said member is composed of a pluralitycf-deaves, and the leaves may-fbe increased ordiminished in number as occasion demands. The bight or .lower portion of the member 4 is arranged in a base casting 25,, having sides apertured'at 28 to receive means-for attaching to an axle of a. vehicle. Arranged between the sides of the base casting, below the apertures 28, is a block; shownby dotted l es i Fi -11 er ltltesasmbafi w Specification of Letters Patent.

Application filed April 28, 1914. Serial No. 884,937.

nected to the base casting and to the said M block by a bolt 26, which extends through the base casting and the several leaves of the member 4, and is threaded into the said 0 block. .Suitably connected to'the innerw leaf ofthe member 4 are channel irons 30 of thin metal stock,- which are designed to receive and guide-the depending portions 7qof the upper member, with a view to holding both 5 the upper member and the lower member against lateral deflection, and also;with a 0g VIBW tO obviating unnecessary wear between theresilient arms 12 of the lowermember and .the resilient arms 7 ofthe upper mem- 7o her-. In addition to the resilient arms 7 ,the upper member comprises a metallic block 6 59 disposed between the upper portions ofthe arms 7 and apertured to receive a boltfor connecting it to the said arms 7, Thesai'd block dis provided with depending portions having a ertures to receive, a pintle 32, 93 through t e medium of which the block is pivotally connected to a member 31. This member 3l has an apertured depending por: tion, and the latter is interposed between and pivotally connected by a bolt 35 to the C3 spaced projections 34 of an arm 33, which latter is designed to be fixedly connected to the body of a vehicle. It will be manifest thatv the'construction described is such as to compensate for any swinging movements that take ,place. It will also be manifest that the frictional contact between the arms 120i the lower member 4, and the arms or dependin portions 7 of the up er member may: be depended on to provide suflicient frictional contact to adequately cushion'the body of the vehicle, to prevent the transmission of shock and jar to saidbody, and .to preclude undue or violent upward movement of the bod with respect to the axle 1 of the vehicle. would further have it mi? derstood at this point that by varying the number of leaves in the lower member 4;,(100 and'the number of leaves in the upper me n' her, the absorber can be fitted to the capacity of;the vehicleor the load that the same is intended to carry on its body.

In the embodiment of my invention shown in Fig. 1 the shock absorber is arranged in or ad acent to an elliptical spring 1 that interposed between and connected with the vehicle axle 2 and the vehicle body 8. It is to-befunderstood, however, that my, novel absorber may 'be interposed between and sweetie e w h att a rate e body at any other point anti hp! a ur proved manner without involving (if:
